I didn't mention, but I'm shopping for a respirator myself. Problem is, no run of the mill respirator will work. I refuse to shave and the multiple certs I had to go through in the Navy and afterwards when working for them have educated me on fit and function. My ONLY choice is a positive pressure system with multiple cartridges. $$$$$$$$$ (I think I have enough of them in there) it's on my list, just below the Uvex Bionic face shield, which was supposed to be this month, but I had to buy rings for my air compressor instead.
